The cause of a fire in Newtown that destroyed a vacant building is undetermined. The fire at the former McGuire’s Ale House/Hot Shots January 14th required all 5 of the volunteer fire companies, plus mutual aid from several surrounding towns. The Deputy Fire Marshal told The Newtown Bee that they're done investigating, unless some new information comes forward. The state helped, with an arson dog, to rule out a location and a cause. The building’s insurance company will further investigate. The fire quickly spread through the entire two-story building, and it became unstable, forcing an exterior attack. An excavator was later brought in to pull down some walls so firefighters could further douse the embers.
